Title: Star cell type core configuration for structural sandwich materials

Full Record
Other Related Research

Abstract

A new pattern for cellular core material used in sandwich type structural materials. The new pattern involves star shaped cells intermixed with hexagonal shaped cells. The new patterned cellular core material includes star shaped cells interconnected at points thereof and having hexagonal shape cells positioned adjacent the star points. The new pattern allows more flexibility and can conform more easily to curved shapes.

Fabrication method for cores of structural sandwich materials including star shaped core cells

Patent Christensen, Richard M [Danville, CA]

A method for fabricating structural sandwich materials having a core pattern which utilizes star and non-star shaped cells. The sheets of material are bonded together or a single folded sheet is used, and bonded or welded at specific locations, into a flat configuration, and are then mechanically pulled or expanded normal to the plane of the sheets which expand to form the cells. This method can be utilized to fabricate other geometric cell arrangements than the star/non-star shaped cells. Four sheets of material (either a pair of bonded sheets or a single folded sheet) are bonded so as to definemore » « less

Sandwich panels with battery cores

Patent Rahn, Christopher D.; Bakis, Charles E.; Hickner, Michael; ...

Systems and methods are disclosed for enhancing the construction and application of batteries by providing a battery system comprising at least one electrochemical panel with at least one electrochemical cell disposed therein, which is configured to enable multi-purpose functionality and applicability of the battery system. Embodiments provide for electrodes and/or current collectors of each electrochemical cell that are transversely orientated with respect to each face of an electrochemical panel. Some embodiments provide for a separator pouch disposed about at least one electrode and/or current collector to electrically insulate the electrode and/or current collector from a structure component of the device.more » « less

Sandwich-type electrode

Patent Lu, Wen-Tong P [Upper St. Clair, PA]; Garcia, Earl R [Ingram, PA]

Disclosed is an improvement on a method of making an electrode wherein a suspension in a liquid is prepared of a powdered catalyst containing a noble metal, carbon powder and a binder, and the suspension is poured over a carbon substrate dried, compressed and sintered to form a solid catalyst layer bonded to the carbon substrate. The improvement is placing a carbon paper on the catalyst layer prior to compressing. The improved electrode can be used as either a cathode or an anode in a sulfur dioxide depolarized electrolyzer in a process for producing hydrogen from water.
